leading manufacturer of deep-cycle batteries, today announced that its
Industrial line of batteries for renewable energy applications has achieved
a major milestone in Trojan's ongoing IEC 61427 testing by surpassing a
15-year cycle life.

Trojan has been conducting IEC 61427 testing on its deep-cycle, flooded
Industrial batteries since October 2010, and results to date show that the
batteries are outperforming their rated 10-year design life. Because
Trojan's deep-cycle batteries are designed to operate at partial states of
charge, the testing parameters being performed involve heavily discharging
the batteries, which is a typical scenario in solar applications. By
stressing the batteries and operating them in this abusive testing
environment, Trojan's goal is to evaluate the overall effectiveness of the
battery line's ability to perform in renewable energy applications where
operating at a partial states of charge is common.

Trojan is following IEC cycle endurance testing parameters based on
photovoltaic applications where the batteries are exposed to a large number
of shallow cycles at different states of charge, inherent in renewable
energy environments. The cycle endurance test is an accelerated simulation
in extreme conditions of the battery's operation in a photovoltaic energy
system, and is conducted by submitting the single 2V cell to a period of 150
cycles. Even though the Industrial line has surpassed the equivalent of a
15-year cycle life test, Trojan's engineering team reports that IEC 61427
testing of the Industrial line is still in progress after 2,250 cycles.

"These ratings illustrate Trojan's authenticity in reporting our battery
life and capacity ratings," said Bryan Godber, Trojan's senior vice
president of renewable energy. "We are pleased to discover that IEC testing
results for the Industrial line surpasses Trojan's published battery design
life estimates. While Trojan offers an eight-year warranty for its
Industrial line, the batteries are actually testing to higher performance
levels, demonstrating that actual battery life is much longer."

The Industrial line supports large daily loads where the batteries are
cycled regularly. The batteries are engineered for high-energy requirements
delivering 1,500 cycles at 80 percent depth-of-discharge, and features
advanced battery technologies that provide optimum performance.

"As installations of off-grid and unstable grid solar applications such as
telecom BTS stations, micro grids, rural electrification and backup power
increase worldwide, so will the need for reliable, deep-cycle batteries for
energy storage," Godber said. "The IEC testing illustrates that Trojan's
Industrial batteries can withstand extreme operating conditions where
continuous deep discharge and recharge of the batteries is typical."
